Home Forums Hunting & Shooting Hunting Rifles Leupold CDS math,

The Factory 'turret' or cap that comes with the scope is MOA?

Someone please tell me how to use MOA to convert to something useful,

In other words, whats the easiest math formula to convert MOA to this example,

10 inches of drop at 300 yards,

school me please.

1 MOA at 100 yards is 1 inch.
1 MOA at 200 yards is 2 inches
1 MOA at 300 yards is 3 inches.

10 ÷ 3= 3.3 MOA

13 "clicks"

I can substitute like this? 10"/300 yards = .03 /.25 = 13?

Same thing but different?

MOA freaks me out. I'm an inches guy........

I think this was the page I went to to get things figured out. Not hard once you figure it out.

(Number of clicks per 1 MOA on scope) x (MOA adjustment) = adjustment in clicks on scope

Figure out your drop in moa on a ballistic calculator then plug it into this formula. Easy squeezy

Or just get the CDS dial in yards and not have to worry about it!

0.25 inch clicks at 100 yards (at 300 each click equals 0.75inch)

10/.75 = 13.33
Or:
4/3 x 10 =13.33

And be shackled to those come ups? No thanks. What if you want to change your load or elevation where you hunt? Just keep buying dials?

OP, stick to a MOA dial.

That there's your problem........

Skip inches and clicks, and don't try to convert anything......think MOA.

Rangefinder says 500 yards, your drop sheet says 5.6 MOA, dial scope to 5 and add two clicks.....boom.....

Like aalf said, forget that other stuff. Get your stuff printed out and on the side of your stock.

Or......quit screwing around with continually altering loads/charges/ bullets, establish a good, working load and use the CDS!

Unless you have some excellent equipment, and shoot at extreme ranges , it’s not a lot of difference between moa and inches. At 1000 yards (a fairly long shot).....10 moa equals 14.7” Unless my math is incorrect! Most of us are incapable of utilizing the difference to an advantage! memtb

1 MOA = 1.047”

So yes, your math is wrong.

If you want to learn long range shooting, you're going to learn either MOA or mils. And as mentioned above, you will just start thinking in MOA, not inches of drop. It seems weird and then all of a sudden it just makes sense.

Regardless, you'll need to write it down and tape it to the side or your rifle or inside of your scope cover.

300 yards ain't that far anyway in the long range game, I think the thick part of the bar of a lot of a lot of 1" Leupy Duplex reticles begins at about 3MOA (at full power), so you might also just use that, depending on your scope and the size of animal you're hunting.

So don’t just tell me I’m wrong.....give me and perhaps others the “correct” answer! memtb

I believe the answer is 10.47

I believe you're missing something. If an moa is "an inch at 100 yards" then it's "10 inches at 1000 yards," so 10 moa is "10 times 10 inches at 1000 yards" which is "100 inches at 1000 yards." Now plug in the 1.047 and you've got 104.7" at 1000 yards.

10.47 " would be at 100yds... as Mathman says at 1000yds it is 104.7", so you bullet would rise 104.7" above line of sight in order to impact dead on at 1000yds
Thanks professor...

That's not really how it goes. Consider the example of a "mid-range" 308 Win. target load, a 168 grain bullet, BC = .45 and MV = 2600 fps. For a 300 yard zero it'll need to be about 5.2" high at 100 which is 5 moa. But the bullet will be about 6.5" high halfway to the 300 yard line.

(inches of drop) / (# yards x 100) / (1.047) = MOA drop

Example: Using 10" of drop at 300 yards,

10 / 3 / 1.047 = 3.18 MOA drop

Hypothetical question: If my understanding of scope adjustments is such that I haven't yet worked out moa vs inches per hundred yards, then am I ready to attempt shots at distances where the difference amounts to much?

REAL World Answer: On a Reupold,you are VERY likely gonna get MOA,IPHY and who knows what the fhuqk else,enroute to a 1K erector solution. Hint. Congratulations?!?

You will also VERY likely encounter a shift in horizontal along the way,with a RTZ shift and more weirdness,as zoom selection changes. Now IF the solutions can/will/do repeat(no matter their cited "values"),then POA/POI can be arranged. If a solution is a 18.75 MOA correction and I know that if I dial my Reupold 18.25,it will corroborate with the requisite and then deeds can be did. Reality is,there's not a bigger piece of fhuqking schit than a CDS or BDC system,especially in Reupold,because none of it tracks accurately. Funnier than fhuqk to hear Boobs extoll the "virtues" of same. Hint. LAUGHING!

Now an elder generation M1 Fixed Reupold,might could do some things that'll repeat,but in them days the reticles and erectors spoke different Languages MOA/MIL. While I'm beyond fluent in same,due to obscene round count,I'd do a Newb THE Favor,to gun Mil's from inception. Tenth's are farrrrrrrr more intuitive and it can easily be applied to Wind Reading,so you get a Wind Reading Finder too. Everyone "thinks" they have to "learn" something "new",but it all stares you in the fhuqking face and is impossible to fhuqk up. An etched reticle that actually subtends the erector's values,will connect dots like no other and doubly so in Mil's. Keep it a Fixed Fhuqker or FFP as a minimum and you ARE there. Hint.

It is FUNNIER than fhuqk,that all here were "convinced" that they "KNOW" what they are talking about,yet none of the DUMB Fhuqks can slide a decimal and all of their First Grade Teachers should be punched in the fhuqking face. The CDS schit is fhuqking hilarious! Hint.

Bless your hearts for TRYING.

Hint.

LAUGHING!.............
